We analyzed the impact of a program that provides indigent patients with free primary care on inpatient admissions, emergency room (ER) visits, and resulting charges in 91 patients before and after admittance into the program. There was a decrease in ER visits after enrolling in the program (1.89 versus 0.83 visits per year; p < 0.0001). This difference translated into mean ER charges of $1,174 vs. $717 (p = 0.0007), and a decrease in charges of $41,587 per year. The charges for the program (outpatient visits and laboratory) were $23,141. Entry into the program had no effect on inpatient admissions, which averaged 0.07 admissions per year both before and after admission to the program. Indigent patients enrolled in a complimentary primary care program had significantly decreased per-year ER utilization rates and charges. The program had no effect on inpatient admissions. By conservative estimate, the program decreased ER charges by approximately $18,000 per year secondary to decreased ER utilization.
